UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented J al1. 30, 1912.

Application med May 15, 1911. serial No. 627,210.

- adaptable for steel cars designed to carry sugar-cane.

-Aside from the general design of the frame, the invention residesparticularly in the construction of the body-bolster and its associatedparts.

In the drawing: Figure 1 is a planview of the improved frame, beingbroken away 1n some placesp for the sake of completer illustration,Figs. 2 and 3 are sectional views upon the planes indicated by the lines2 2 and 3-3 in Fig. 1, and Fig. 4 is an end view.

The side-sills a and end-sills b of the frame lmay consist of channelsas shown, and the center-sill c, which extends-between the body-holstersd, preferably consistsv of a relatively broad I-beam, the center-sillbeing continued to the end-sills by draft-sills i ey which, as shown,are channels of the same size as the side and end sills. Between .thebody-holsters, the frame is preferably braced by means of transversechannels f,

, braces shown in Fig. 2 as being less in depth than the .side andend-sills, and by diagonal angle g. The frame is also shown as `beingbraced at the ends by diagonal channels k .extending from the center ofthe bodyholsters respectively to the corners vof the frame,

The body-holsters d, formed m-the case *ofthe present .embodiment of theinvention VofI-beams, are each divided near their midsill.' l1n `mostcases it will bepreferable' to `I extend the Z-irons inwardly beyond theends of the draft sills in order to provide an eX- tra fastening surfacewhereby they may be the more securely riveted to the center-sill, asshown in Fig. 1. By means of such a connection between the centersillandthe draft-sills upon either side thereof, a very strong and durablebody-bolster is provided and one which resists to a great degree thebending and warping strains to which the frame is subject in use.Moreover, the draftsills are thus very firmly, as well as simply, unitedto the center-sill and body-bolster -and virtually become a part of thelatter. To further unify and strengthen the bodybolster the usual topand bottom coverplates, f: and Z respectively, are "applied v above andbelow the same as shown.

I claim as my invention: l. A .steel underframe for cars having acenter-S111; a palr of draft-sills one on each side of the center-sill,and a Z-iron between each draft-sill and the center-sill to secure theone to the other.

. 2. A steel underframe for cars havingv an I-beam center-sill, a pair'of channel iron draft-sills one on each side of the center-sill, and aZ-iron between each draft-sill andthe lcenter-sill and riveted thereto.

3. A steel underframe for cars having a center-sill, a pair of channeliron draft-sills at .each end of the center-sill, and a Z-iron betweeneach draft-sill and the center-sill. to secure the one to the other.

4. A steel underframe for cars having a center-sill `consisting of anI-be'am, a pair of draft-sills one on each side of. the I-beam andextending 'beyond the I-beam at each end .'t'hereof, and a' Z-ironbetween each draft-sill and the I-beam to secure the draftsills to the-Ibeam.

5. A steel underframe for cars havingan I-beam center-sill terminatingatpoints intermediate the ends of the frame, a pair draft-sills one oneach side ofthe centerill at each end of the center-sill and continuingthe center-sill to the ends of the frame, a Z-ironriveted between eachdraft sill and the center-sill,.and transverse I-beams eX- tending fromthe inner ends of the draft sills to the sides of the frame.

6. A ,steel underframe for cars having an I-beam center-sill terminatingat points intermediate the ends'of the frame, a pair of draft-sills oneon each side of the centersill at each' end of the -center-sill landcon- Q 1,0m, :Les
